`CONVEYER ROLLER.

Application led September 29, 1924. Serial No. 740,588.

To all whoml it may cio/mem.' A

Be it known that'I, GORDON W. BEULKE, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have vinvented new and usefiil Improvements in Conveyer Rollers, ofwhich the following is a specification.

This invention relates to conveyer rollers and p'artidiilarly to rollerswhich are revoluble upon rods extending axially therethrough, and ,fixedat their ends in supporting side railsl The object of this invention isto provide inexpensivev and eilicient means for securing the supportingrods forpsuch rollers to the side rails. l,

More particularly, vide lnovel fastening means adapted to transmit enthrust to the rails while permitting quick and easy insertion andremoval of the rollers.

Infthe accompanying drawings, which illustrate the best form of mydevice at present known to me, Fi ure 1`is a side elevation of theinvention, s owing the roller partially in central, vertical section;Fig. 2 1s gether with a fragmentary portion of one of, the supit is myvobject to profor the rods porting rails; and Fig. 3 isA anenlargedperspective view of an end of the anual rod.

.Referring to the drawings, I have used the numeral 4 to indicate the`roller body which is provided in each end with a recessv for ananti-friction bearing 5 adapted to transmit end thrust to a sleeve 6 uon an axial rod 7. This rod 7 is supporte at its lends in a pair of.,side rails 8 connected by transverse frame members 9..

The rod 7 is circular in cross section throughout its length withexception of a short' flattened ortion 10 near one end. One of the rais8 has a punched hole formed to fit the flattened end of the rod 7, Whilethe opposite rail has a circular hole throng which the rod 7 may be in=serted. Near its outer extremity,'close tothe face of the rail, theportion l() has a perforation 11 adapted to receive `a 'stout Cotter key12. This key 12 revents accidental removal'of the rod -7 rom the railsand roller and constitutes an abutment for end thrust in one direction.End thrust in the opposite directionistransmitted to one revent rotationthereof and to lof the rails 8 by a shoulder 13 at the inner end of theportion l() of the rod 7.

As will now be readily understood, the roller 4 may be quickly andeasily mounted between the rails 8 (said rails have been previouslyjoined in parallel relation by the member 9) by merely inserting the rod7, flat and foremost, successively through the rail having a circularperforation, axially through the bearing sleeves 6, and then into thenon-circular hole in the rail at the right, as shown in Fig.v 1. lVhenthe cotter key 12 4is finally placed'in the perforation 11 and securedtherein in the usual manner, the roller is held in spaced relation withthe side rails, end thrust being transmitted -to ple of the rails bythekey.12 and shoulder It will be noted that the sleeves 6 maintain theroller 4 in proper spaced relation to the rails 8, but were the key 12or shoulder 13 omitted, end thrust applied to the roller would cause therod 7 to work out of its bearings in the rails. In order to insureuniform wear on the sleeves 6, it is necessary to allow said sleeves torotate slowly or creep upon the rod 7. A rod which is circular in crosssection within the sleeves 6. is, therefore, practically essential toeicient working of the bearings. Qbviously, rotation :of the.v rod 7 inthe rails is prevented by the flat portion 10 which fits' the punchedhole in the rail. tween the rod and 'rails is prevented and unusuallyfree rotation and secure mounti fr of the roller is obtained.

Thus wear beaving described my invention what I claim as new and desireto protect by Letters vPatent is: v

1. The combination` with a roller adapted to be journalled betweenappair ofside rails, of a circular rod extending. axially through saidroller and arrangedto be supported at its ends in said rails, said rodbein adapted to be withdrawn longitudinally 11i-said rails withoutseparationof Said rails, a noncircuiar portion on an end of said roddisposed to project through, and fit within, a

ole in one of said rails whereby said rod is prevented from turning insaid rails, and removable fastening means on the projeetin end of saidnon-circular portion adapte to prevent longitudinal withdrawal of saidrod from said rails. 1`

2. The combination with a pair of rails "1n saidrod for engagementrigidly Vconnected one non-circular" portion rod adapted to fit withinan opening in one of said railswhereby said rod is prevented 4formed insaid rod circular portion, adapted to constitute ay rigidly connectedone to the other in parallelrelation, of a roller adapted-to berevolubly mounted between said rails, a rod extending axially throughsaid roller and arranged to be supported vat its ends in said rails, oneend of said rod being free for lon 'tudinal movement in one of saidrails', a s oulder .formed with lthe inner surface of the other of saidrails, said shoulder constituting a stop for end movement ofsaid'rodin'one'direction and removable means engaging said rod adjacentto the outer l adapted to prevent' longitudinal Withdrawal of said rodfrom said rail in the opposite direction. o

3. The combination lvvith'a pair of rails to the other in parallelrelation, of aroller `adapted to be revolubly mounted betweenSaidrail's, a rod extending axially through said roller and arranged tobe supported at its endsl` in said rails, a near an end of said fromturning in saidY rails, the other end of said rod being xfree forlongitudinal movement in the other of said rails, a shoulder adjacent tosaid nonstop for longitudinal movement of said rod in one dlrection andremovable means en surface' of said lastmentioned rai-l,`

ing a stop for end l gaging said rod adjacent to the outer surface ofsaid last-mentioned rail adapted to prevent longitudinal Withdrawal ofsaid rod in the opposite direction.' g

4. The combination with a roller adapted to be journalled between a pairof Side rails, of a rod extending axially through said roller andarranged to be supported at its ends in said rails, bearing sleevesrevoluble on said rod adjacent to the inner surfaces of said rails, andarranged to transmit end thrust to the rails, anti-friction bearingsrevoluble upon said sleeves and adapted to coact therewith intransmitting end thrust from the roller to said rails, a non-circularportion on one end only of said rod, disposed to project through and titwithin a hole in one of said rails, whereby said rod is prevented fromturning in said rails, a shoulder formed in said rod-adjacent to Saidnon-circular portion for engagement with the inner surface of one ofsaid rails, said shoulder constitutmovement of said rod in one directionand removable means engaging said lrod adjacentto the outer surface ofsaid last mentioned rail, adapted to prevent Withdrawal of said rodlongitudinally in the other direction.

In testimony whereof, I have hereunto signed my name to thisspecification.
